Style sheets are actually the format designed for particular site or web page. The file usually named style.css is the main file for implementing all the CSS effects. sometimes if you download any template it may have online CSS i.e. it may run correctly with its all the styles only when you are online.
These style sheets may contain different ids and classes represented by # and . respectively. Each id belongs to only one parameter of the code while the class may refer to multiple parameters where same effect is needed.
